# Linksy

> Linksy connects an Android phone and a Linux computer directly over your own network: files and folders, the clipboard, screens both ways, a tablet or phone as a second display, the phone as a webcam (up to 1080p at 60 fps) and as a microphone, a terminal on the computer from the phone, and away from home over an end-to-end encrypted connection. Free and open source (GNU AGPL v3 or later), no account, no cloud.

## Key facts

- Platforms: Linux (x86_64, GTK 4.14+, libadwaita 1.5+; works on GNOME, KDE Plasma and other desktops) and Android. No Windows, macOS or iPhone.
- Current Linux version: 0.9.2. Packages: Flatpak, .deb, .rpm (Fedora, openSUSE), tarball; the .deb and .rpm come as linksy-common plus linksy (GTK, GNOME and most desktops) or linksy-qt (KDE Plasma 6). Flathub and the AUR are coming.
- Any number of devices: each pairs once on the same network (QR code or six-digit code), then every device can reach every other.
- Encryption: QUIC with TLS 1.3, keys pinned at pairing.
- Away from home: devices that met on the same network in the last 7 days reach each other over the internet, directly when possible, otherwise through an open-source iroh relay that forwards encrypted packets at most 16 KiB/s per device and stores nothing.
- Not yet: phone notifications and texting on the computer (Android restricts that access for apps installed outside an app store). Not planned: the computer's sound played on the phone.
- An alternative to KDE Connect / GSConnect, DroidCam and AudioRelay in one app.
